BackgroundIC50: 170 nM2-cyano-Pyrimidine is a cathepsin K inhibitor. Cathepsin K is a protease defined by its high specificity for kinins, which is involved in bone resorption. Cathepsin K"s ability to catabolize collagen, elastin, and gelatin allow it to break down bone and cartilage. Such catabolic activity is also partially responsible for the loss of lung elasticity and recoil in emphysema. Therefore, inhibitors of Cathepsin K are showing great potential in the treatment of osteoporosis.In vitro: 2-cyano-Pyrimidine was identified as a cathepsin K inhibitor whose basic structure and derivatives have been evaluated for the treatment of osteoporosis. Enzymatic study showed that 2-cyano-Pyrimidine had an IC50 value of 170 nM for inhibition of cathepsin K, elevated activity of which has been linked to the formation of osteoporosis and arthritis. Moreover, Cathepsin K was found to be a lysosomal cysteine protease found in osteoclasts.
